Kono Subarashii Sekai ni Shukufuku wo!, Tate no Yuusha no Nariagari Recommendations
If you enjoy fantasy genre anime with a well structured hero's journey, then you will most likely love both of these shows. Both follow a protagonist who was an outsider in our world, and after an unfortunate series of events, has ended up inside a fantasy world which they must save. Both of these shows absolutely engrossed me with their fantastic world building and relatable main characters.
Main characters are teleported in a fantasy/RPG world.
They have difficulties to find their place in this world.
They are not overpowered when they begin their adventure.
Twice are recent anime with good animation.
KonoSuba is parody of that kind of anime, Tate no Yuusha is a lot more serious.
